Every SaaS developer building a multi-tenant app has to solve the same problem: how do you isolate files per user, enforce storage quotas, and track usage without rolling your own logic? Tenantbox solves this in two API calls. → Request a presigned URL with a tenant_id → PUT the file directly to Tenantbox storage, your server never touches it. That's it. Tenants are created automatically on first upload. Quota enforcement is built in. Per-tenant usage tracking works out of the box.
Hey Product Hunt! 👋
I'm Hemstone, the solo developer behind TenantBox.
I built this because I kept solving the same problem across every SaaS project I worked on per-tenant file isolation, quota limits, usage tracking. It's boring infrastructure that every multi-tenant app needs but nobody wants to build from scratch.
TenantBox handles it in two API calls. Files go directly to Tenantbox storage via presigned URLs your server never sees them, so uploads are fast and you pay $0 in egress fees. Tenants are created automatically on first upload.
It's in beta right now and completely free to try. I'd love to hear from anyone building a SaaS product what does your current file storage setup look like? Happy to answer any questions below. 🙏
